Biocompatible Two-dimensional Titanium Nanosheets for Efficient Plasmonic Photothermal Cancer Therapy [PDF]

arXiv, 2018
Photothermal therapy (PTT) has shown significant potential in cancer treatment. However, developing nanomaterial-based photothermal agents with good biocompatibility and high photothermal conversion efficiency (PTCE) remains a key challenge. Titanium has been widely employed as biomedical materials based on their excellent biocompatibility.

Flexible and biocompatible microelectrode arrays fabricated by supersonic cluster beam deposition on SU-8 [PDF]

, 2010
We fabricated highly adherent and electrically conductive micropatterns on SU-8 by supersonic cluster beam deposition (SCBD). This technique is based on the acceleration of neutral metallic nanoparticles produced in the gas phase. The kinetic energy acquired by the nanoparticles allows implantation in a SU-8 layer, thus producing a metal-polymer ...

Modification of poly(L-lactide) and polycaprolactone bioresorbable polymeric materials by RF plasma discharge: a preliminary study evaluating EA-hy 926 cell attachment [PDF]

arXiv, 2014
Surface modification of poly(L-lactide) (L-PLA) and polycaprolactone (PCL) bioresorbable polymers by radio-frequency thermal glow discharge plasma is reported. Improved biocompatibility of L-PLA and PCL materials was obtained by employing hydroxyapatite target sputtering in Ar+ plasma as evidenced by the change of L-PLA and PCL properties from highly ...
